SUPPORT FOR WOVEN-WIRE *IVIATTRESSES.

Specification of Letters Patent.

Patented Dec. 25, 1906.

' Application m d March 30,1906. Serial No. 308,961.

' condition, thereby to render the same either illustratinglthe relation of a support with restiff or yieldable, as may be desired.

A further object of the invention is to arrange the supportingdevices so that all tension may be relieved therefrom in order that the frame of the mattress will not become warped when in storage and in transportation and to enable the convenient placing of tension upon the device when the mattress is set up in condition for use. 1

With these and other objects in view th present invention consists in the combination and arrangement of parts, as will be hereinafter more fully described, shown in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that changes in the form, proportion, size, and minor details may be made within the scope of the claims without departing from the spirit orsacrificing any of the advantages of'the invention.

In the drawings, Figure 1 is an inverted plan view of one corner portion of a conventional form of woven-wire mattress equipped with several supporting devices of the present invention. ig. 2 is a longitudinal sectional view taken through the mattress and spect to t e wire fabric. Fig. 3 is an enlarged detail perspective view of one of the supports of the present invention.

Like characters of reference designate corresponding parts in all of the figures of thedrawings.

Referring at first more particularly to Fig. 3 of the drawings, it will be noted that the present support includes a spring member made up of a spring-coil 1, having several whirls-say, for instance, threefrom which the end portions of the spring diverge and constitute arms 2 terminating at their outer ends in hooks or eyes 3. For the support of the spring there is a substantially U-shaped clip 4, preferably of wire, which is passed through the spring and has its ends terminating in hooks or eyes 5. Links 6 are loosely connected to the hooks or eyes 3 of the arms eyes 7 engaged with the hooks or eyes 3, the forward ends of the links being passed through openings 8 in a cross-head 9, preferably m t e nature ofa rectangular plate stood on edge in a vertical position. The links work loose in the perforations 8 and are held against rearward displacement therethrough by means of heads or enlargements 10, preferably formed by bending the ter minals of the links to form eyes. A threaded ening in the cross-head 9 and is provided at its forward end with a hook 12 and at itsrear end with a winged nut 13, bearing against the rear side of the cross-head. A wire 14, having a terminal loop 14, is engaged with -the hook 12 and is of suitable length, according to the length of the mattress to which the device is to be applied.

In practice the present support is applied to a mattress, as shown in higs. .1 and 2, wherein 15 and 16 designate the end bars of the frame of a conventional woven-wire mattress, said bars being connected at corremanner, and any appropriate form of woven-Wire fabric 18 is connected to and stretched between the end bars 15 and 16 of the head and attached thereto in any suitable manner. With mattresses of this character it is necessary to support the intermediate portions thereof, so asto revent undue sagging, and this is accomp ished by means of the present device, a plurality of which are disposed in substantial parallelism beneath 15 and 16. Each clip 4 embraces one of the of a suitable fastening 19, piercing the end bar and the eyes 5 of the .cli while the outer end of the wire 14 is suita ly connected to the opposite end bar 16. When the mattress 1s in storage and transportation, there is no tension upon the supporting devices; but when the mattress is set up for use the winged nuts 13 are tightened, so as to place the tension upon the several supports for the preventing undue stretching thereof. The degree of rigidity of the fabric may be varied by manipulation of the nuts 13 and one-half 2, preferably by having terminal hooks or' the mattress and connected to the end bars.

purpose of supporting the wire fabric and stem 11 passes loosely through a central op- I sponding ends by a side bar 17 in the usual end bars and is connected thereto by means ICC of the mattress may be maintained in a relatively rigid condition by tightening certain of the nuts, while the other half of the mattress may be supported in a relatively loose condition by loosening certain of the nuts.

From the foregoing description it will be understood that the device of the present invention is entirely complete in itself and capable of being fitted to any ordinary form of woven-Wire mattresses Without making any alteration therein. Moreover, the supports may be adjusted to a slack condition when the mattress is not in use, thereby to avoid warping of the frame under unnecessary tension, and the supports may be placed under tension in a very simple and convenient manner for the purpose of supporting the woven-wire fabric with any degree of rigidity according to the Wish of the user of the mattress.

Having thus described the invention, what is claimed is 1. The combination with a wove1i-wirc mattress and its frame, of a resilient support including spring-arms connected to one end of the frame, a rod connected to the other end of the frame, and an adjustable device connecting the rod and the arms to vary the ten sion of the device. t

2. A support for woven-wire mattresses comprising spring-arms for connection with one end of the frame of the mattress, a rod for connection with the other end of the frame, and a threaded connection between the rod and the arms for varying the tension upon the device.

3. A support for woven-wire mattresses comprising spring-arms for connection with one end of the frame of the mattress, a rod for connection with the other end of the frame, a cross-head connected to the arms, a threaded stem carried by the rod and loosely piercing the cross head, and an adjustingnut carried by the threaded stem and bearing against the cross-head.

4. A support for woven-wire mattresses comprising a spring-coil having opposite arms, a clip engaged With the coil for connection with one end of the frame of the mattress, links loosely carried by the ends of the arms, a cross-head carried by the links, a rod for connection with the other end of the frame and including a threaded element loosely piercing the cross-head, and an adjusting-nut carried by the threaded element and engaging the cross-head.

5. A support for woven-wire mattresses comprising a spring-coil having opposite arms, a substantially U-sha )ed clip engaging the coil for connection with one end of the frame of the mattress, links loosely carried by the ends of the arms, a cross-head loosely carried by the links, a Wire for connection with the other end of the frame and provided in its inner end with a loop, a hooked threaded stem engaged With the loop and loosely piercing the cross-head, and an adjustingnut carried by the threaded stem and bearing against the cross-head.

In testimony that I claim the foregoing as my own I have hereto aiiixed my signature in the presence of two Witnesses.
